SPECIFICATION forming part of Letters Patent. 322,269, dated July 14-, 1885.-

Application filed May 6, 1884. (No model.)

i To all whom it may concern.-

k lowing, together with the accompanying drawings, forms a specification.

My invention relates to improvements in pumps, and is more particularly applicable to steam-pumps used for forcing water against. high heads, such, for instance, as are used in certain mining operations.

In the ordinary forms of steam-pumps the valves are placed in a fiat valve-plate, which,

in order to resist the high pressure and severe oftime;

.riphery of which the valves are placed. Due .to the shape of such cross-section, these valveshock to which such plates are subjected, must be made very heavy. In practice these plates are often fractured, and to replace them requires that the whole pump be taken apart. This necessitates considerable expense and loss The object of my improvement is to replace the flat valve-plate as ordinarily found in pumps by a valve-pipe of circular, elliptical, polygonal, or similar crosssection, on the pe pipes will be able to resist much higher pressures than the ordinary flat valve'plates. These valve-pipes also are so arranged as to be readily-removed, and so that they can be quickly replaced in case of accident or injury, or when valve-seats or valves are worn, by simply removing a bonnet held in place by bolts, thus saving considerable delay and expense. I attain these objects by the use of the construction illustrated in the accompanying drawings, in which-- Figure 1 represents a central vertical longitudinal section of a pump embodying the features of my invention. Fig. 2 represents a vertical central transverse section of the pump on line 00 as, Fig. 1. Fig. 3 represents a vertical transverse section of the pump on line 3/ 'y of Fig. 1. Fig. 4 represents a vertical longitudinal section of a modified form of pump embodying the features of my invention. This section is taken in three parallel planes, as shown by lines 2 z, o o, and 'w w of Fig. 5. Fig. 5 represents a vertical transverse section of the pump illustrated in Fig. 4, the section being taken along line it u in Fig. 4.

Two differently-arranged pumps embodying the general features of my invention are illustrated in the accompanying drawings and will not be described, the first method of construction being shown' in Figs. 1, 2, and 3.

This pump is made in three main pieces or V V each communicating with one end of pump-cylinder 0 through valves 1) and ports 1) and 12 These valve-pipes are virtually a coir tinuation of the suction-pipe into, the suctionchamber of the pump. As before stated, these valve-pipes can be made of any desired or convenient cross-section. Valves of any ordinary or desired construction are fitted on at t, Fig. 3. From each valve-pipe V V the water passes through valves 12 and ports pand' p alternately into the corresponding end of the pump-cylinder 0, according to the direction in which the piston P is moving. The water is then forced through ports p y into the valve-pipesV V, projecting into the discharge-chamber, as shown in Fig. 1. Through the valves '0 011 the valve-pipes VFVthe water passes into the discharge-chamber D and is discharged from the pump into the forcemain at d.

The valve-pipes are secured in the suctionand discharge chambers in any suitable manner. I prefer to form them closed at one end and with. flanges f at the other end, as shown in the drawings. All four valve-pipes can, if

desired, be made alike and interchangeable. The valve-pipes, by'flanges f, are bolted to flanges or ribs 6 e in suction-chamber and to flanges or ribs 9 g in the discharge-chamber,

, ready for use, thus greatly reducing the delay necessary in case of breakage. Any usual form of valve can be used in such valve-pipes.

The seat of the valve can be'formed either di rectly on surface of pipe or a removable valveseat may be screwed or otherwise suitably secured in opening in valve-pipe.

In the construction illustrated in Figs. 4 and 5 we have, as before, a pump consisting of three main pieces or castings. The cylinder 0 is secured between the double suction-chamber S below and the discharge-chamber D above. The suction enters the two suction valvepipes V V at one end of the pump through double T B and passes alternately through valves 22 and ports 1) and p at each end and side of the cylinder 0, according to the direction in which the piston is movin Through the ports 1) and p the water passes into the discharge valve-pipes V V*, through valve 1; into the discharge-chamber D, and is finally discharged from the pump into the foreemain at d. v

In this construction as in former the valvepipes are formed closed at one end and with flanges f at the other end. Instead of being placed end to end, as in previous construction, the valve-pipes are made of smaller diameter and. are placed side by side, each one extending the full length of the cylinder. The valve-pipes are secured in place by flange f being bolted between flange at end of suction-chamber and flange of double T B, and between flange at each end of discharge-chamber and bonnets L. These bonnets have ports connecting the discharge valve-pipes with ends of cylinder.

Inboth constructions hand-holes m are provided at each side of suction and of dischargechambers, through which access can be had to any of the valves 21. I

I have shown only one valve-pipe in each section of the suction and discharge chambers. Two or more similar valve-pipes could, if desired, be used in each section. This, however,

would only be desirable in larger pumps.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a pump, a movable valve-pipe pr0- vided with outwardly-opening valves on its periphery closed at one end, connected directly at its open end with the suction-main and extending into the suction-chamber, substantially as shown and described.

2. The combination, in a pump, of a suction-chamber having a removable bonnet, a removable valve-pipe provided with outwardlyopening valves on its periphery closed at one end, connected directly at its open end with the suction-main and extending into the suction-chamber, substantially as shown and described.

3. The combination, in a pump, of a cylinder and piston, suction and discharge chambers provided with removable bonnets and communicating with the cylinder, a removable valve-pipe closed at one end and provided with outwardly-opening valves on its periphery, said pipe communicating at its open end with the suction-main and extending into the suction-chamber, and a removable valve-pipe closed at one end and provided with outwardly-opening valves on its periphery, said valvepipe communicating at its open end with the cylinder and extendinginto the dischargechamber, all arranged and operating substantially as shown and described.

4. The combination, in a pump, of a suction-chamber, S, having removable bonnets a a removable valve-pipes V V closed at one end and provided with valves '0 on their pe ripheries, said valve-pipes communicating at their open ends with the suction-main and extending into the suctioirchamber, a cylinder, O, having a piston, P, and communicating at its opposite ends with the suction-chain ber, a dischargechamber, D, communicating with opposite ends of the cylinder 0, and pro vided with removable bonnets a (4*, removable valve-pipes V V*, closed at one end and too provided with valves 2) on their peripheries, said valve-pipes communicating at their open ends with the cylinder 0 and extending into the discharge-chamber, all arranged and op erating substantially as shown and described.
